Use screws specifically rated for cement board: corrosion-resistant with a drill point and a low-profile head that sets flush without cracking the board. Standard drywall screws are not suitable because they rust in wet areas and lack the correct tip.

No. Drywall screws are not rated for cement board installation. They lack corrosion resistance for wet areas and do not have the drill point needed for cement board dense material.

Most cement board manufacturers specify screws at 8-inch intervals in the field (center of the board) and 4-inch intervals at the edges and ends where boards meet. Follow the specific backer board manufacturer installation guide.

Yes. The screw head should be driven flush with or just below the surface of the cement board without cracking the board surface. A countersunk or raised head under the tile will cause an uneven tile surface.

Yes. Our tile backer screws have a corrosion-resistant coating designed for wet-area applications including showers, tub surrounds, and bathroom floors where standard steel screws would rust.

Our tile backer screws use a Torx star drive. The Torx drive provides the cam-out resistance needed when applying the torque required to drive through dense cement board material.

Yes. Our cement board screws are compatible with HardieBacker, Durock, and other major cement backer board brands. Check the backer board manufacturer specification for screw requirements to confirm.

No. The drill point tip on tile backer screws penetrates through the cement board and into the wood framing without pre-drilling. Using a screw with a drill point is important for clean installation without cracking the backer board.

Using standard drywall screws or uncoated screws in cement board applications leads to rust bleed-through, which can stain grout and cause tile adhesion failure over time. Always use cement board-specific corrosion-resistant screws.
